Today, a gall midge slipped from a gall on blackberry. I think it is Lasioptera rubi. However, there are also inquilines in this galls and it could also be Clinodiplosis socialis. I have not seen both types and therefore they do not differ too. Who can help me?

Thanks Volker

It is consistent with Lasioptera and not with Clinodiplosis.

Cecodomyiidi have longer antennae.

Hi John

Lasioptera belongs to the family Cecidomyiidae, but my midge has short antennae.

Greetings Volker

Note ending of "family group" names.

Cecidomyiidae (family) is divided into 3 or 5 subfamilies.

Cecidomyiinae (subfamily) is conventionally divided into supertribes. This is the only group of Diptera where supertribes are in common use. There are two supertribes in Europe.

Cecidomyiidi (supertribe) males generally have very long antennae with 24 apparent segments separated by narrow stems. Females have 12 segments with short stems. The antennae are longer than your fly's.

Lasiopteridi have a variable number of flagellomeres. In Lasioptera the antennae are very short.
